Replacement verdict
Compatible functional replacement candidate
The ADC128S022CIMTX is a tape-and-reel packaged variant of the ADC128S022CIMT and is a compatible functional replacement candidate. Both parts share identical device specifications, differing only in packaging format and ordering quantity, so the CIMTX can be used wherever the CIMT is specified, provided reel-based assembly handling is acceptable.

Frequently asked questions
What is the difference between ADC128S022CIMT and ADC128S022CIMTX?
The ADC128S022CIMT and ADC128S022CIMTX are the same Texas Instruments 8-channel, 12-bit successive-approximation ADC in a TSSOP-16 package. The "X" suffix denotes a tape-and-reel packaging option, while the non-X part is typically supplied in tubes or trays. Electrical and functional specifications are identical.
Are the ADC128S022CIMT and ADC128S022CIMTX electrically and functionally interchangeable?
Yes. Both orderable part numbers share the same die, pinout, TSSOP-16 package, and datasheet specifications, including 12-bit resolution, 8 input channels, and a serial interface. The only difference is the shipping/packaging format, so they are interchangeable in a design.
What are the key specifications of the ADC128S022?
The ADC128S022 is a 12-bit, 8-channel successive-approximation ADC with a serial (SPI-compatible) interface, operating from a 2.7 V to 5.25 V analog supply. It offers conversion rates up to 200 kSPS and is specified over the -40 °C to +105 °C industrial temperature range in the TSSOP-16 package.
What does the "X" suffix on ADC128S022CIMTX indicate?
The "X" suffix is a Texas Instruments packaging designator indicating tape-and-reel delivery. It does not indicate a different silicon revision, temperature grade, or electrical specification compared with the ADC128S022CIMT.
Can ADC128S022CIMT and ADC128S022CIMTX be used on the same PCB footprint?
Yes. Both parts use the identical TSSOP-16 package with the same pinout and land pattern, so either orderable part number can be assembled on the same PCB footprint without layout changes.
Which part number should be selected for high-volume automated assembly?
For high-volume automated pick-and-place assembly, ADC128S022CIMTX (tape-and-reel) is generally preferred because it is compatible with automated reel-fed placement equipment. ADC128S022CIMT is typically used for prototyping or lower-volume runs where tube or tray packaging is acceptable.
Do both parts share the same operating temperature range and interface?
Yes. Both ADC128S022CIMT and ADC128S022CIMTX are specified over the -40 °C to +105 °C industrial temperature range and provide the same SPI-compatible serial interface, since they are the same device offered in different shipping formats.
